Re: 5G
That's a good comment TV Monitor, which illustrates some of the decisions the industry needs to take.

It's not only the Koreans that are interetsed in 28GHz, but Samsung is pushng that hard.

Re: 5G
As you and Brown both illustrate, there are pros and cons to both spectrum brands. Neither is a silver bullet. it will be interesting to see how it shakes out when hype gives way to actual deployments across the globe.

5G
About low-band 5G, it's a lot easier to implement than the high-band 5G but it will have to compete with LTE-A in the market place, and the advantage of low-band 5G isn't clear aside from low latency for real-time applications. Low-band 5G's spectral efficiency is supposed to be 30% better than LTE-A's, but is that enough to justify a massive new infrastructure investment especially when the bandwidth is extremely hard to come by below 6 Ghz without stealing from the 5 Ghz WiFi band where 5 Ghz WiFi, LTE-U, and Low-band 5G have to compete for available channels, and end users cannot perceive immediate benefits relative to LTE-A or LTE-U.

The high-band(28 Ghz) 5G as being pursued by Koreans is much harder to implement, but the end user benefit is much more obvious, 7 ~ 10 Gbits end-user throughputs that makes 4K youtube streaming possible. But since Koreans are the only ones pursuing the high-band 5G before 2020, the equipment cost will likely be high and the available handsets only come from Samsung and LG, no Apple iPhone or Chinese phones.
